- Notice that these four meiocytes are genetically different from one another. In humans (2 n = 46), who have 23 pairs of chromosomes, the number of chromosomes remains unchanged from the beginning till the end of meiosis II (n = 23). Prophase II. Spindle fibers reform and attach to centromeres in prophase II.

Mitosis Vs. Meiosis If a haploid cell undergoes mitosis, which is something certain types of plant and fungus do as part of their normal life cycles, the end result is two identical haploid cells (n→n). In meiosis, however, you start with a diploid cell that divides twice to produce four haploid cells. In other words a diploid cell that has 2n chromosomes produces four cells, each of which contains n chromosomes. Now let's step back and talk briefly about chromosomes. Most of the time, each chromosome is a single, long molecule of DNA.

- While mitosis produces 2 daughter cells from each parent cell, meiosis results in 4 sex cells, or gametes in males and 1 in females. Unlike the cells created by mitosis, gametes are not identical to the parent cells. In males, meiosis is referred to as spermatogenesis because sperm cells are produced.

How many chromosome are in each daughter cell at the end of meiosis I? Rating Newest Oldest. Best Answer: Prior to meiosis I, there are 46 chromosomes, each with two chromatids (total of 92 chromatids). At the end of meiosis I (the reduction division), there will be 23 chromosomes (each having two chromatids, for a total of 46 chromatids) in each cell.

Learn About the Stages of Meiosis Meiosis is a two-part cell division process that produces sex cells with one half the number of chromosomes as the parent cell. There are two stages or phases of meiosis: meiosis I and meiosis II. At the end of the meiotic process, four daughter cells are produced.

What is created by mitosis and meiosis? In Mitosis, two identical Somatic (body) cells are produced. In Meiosis, there are two possible outcomes. For sperm, 4 identical gametes (sex cells), or spermatozoa, are created. For eggs, 1 gamete is produced, and 3 polar bodies are produced (since there is only enough cytoplasm for one cell to live).

Meiosis The end result is production of four haploid cells (n chromosomes, 23 in humans) from the two haploid cells (with n chromosomes, each consisting of two sister chromatids) produced in meiosis I. The four main steps of meiosis II are: prophase II, metaphase II, anaphase II, and telophase II.

Meiosis, inheritance and variation During meiosis in humans, 1 diploid7 cell8 (with 46 chromosomes9 or 23 pairs) undergoes 2 cycles of cell division but only 1 round of DNA replication10. The result is 4 haploid11 daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes – 1 from each pair in the diploid cell). At conception, an egg cell and a sperm cell combine to form a zygote12 (46 chromosomes or 23 pairs).

Learn About the Stages of Meiosis In telophase II of meiosis, the following events occur: 1  Distinct nuclei form at the opposite poles. 2  Cytokinesis (division of the cytoplasm and the formation of two distinct cells) occurs. 3  At the end of meiosis II, four daughter cells are produced.

How many cells are produced in Mitosis and Meiosis? Best Answer: mitosis 2n meaning you get 2 of the same identical cells of chromosomes from the parent so diploid. meiosis n meaning you get half of the chromosomes from each parent so haploid. 4 cells.

Meiosis: Production of gametes Products of meiosis II. The four cells that result from meiosis II contain half the number of chromosomes. In humans two cells contain an “X” and two contain a “Y”. Because of recombination during the meiosis I (discussed in another article) the gametes are genetically different.

Meiosis In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as Meiosis I and Meiosis II.

meiosis Cytokinesis follows, dividing the cytoplasm of the two cells. At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.This process is required to produce egg and sperm cells for sexual reproduction.During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.ytokinesis follows, dividing the cytoplasm of the two cells. At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.

Contents: Mitosis and Meiosis Cells prepare for division by replicating DNA and duplicating protein-based centrioles. When cell division begins, the cells enter into either mitotic or meiotic phases. In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.

- Best Answer: A) Mitosis produces 2 diploid cells, or 2 offspring. If a cell goes through mitosis, the ideal result is the two offspring each have the same number of chromosomes as the parent. B) There are 12 in total after 3 diploid cells go through meiosis. Meiosis produces 4 offspring since it goes through divisions (Meiosis I and Meiosis II).

CELL DIVISION: MEIOSIS AND SEXUAL REPRODUCTION Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division). Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division). Most of the differences between the processes occur during Meiosis I.

Meiosis Meiosis produces haploid gametes with one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes.he end result is production of four haploid cells (n chromosomes, 23 in humans) from the two haploid cells (with n chromosomes, each consisting of two sister chromatids) produced in meiosis I. The four main steps of Meiosis II are: Prophase II, Metaphase II, Anaphase II, and Telophase II.
